Product Description

General Description 

The MP9447 is a fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution to achieve a 5A, continuous-output current over a wide input-supply range with excellent load and line regulation. It also provides fast transient response and good stability for wide input-supply and load range. The MP9447 operates at high efficiency over a wide output current load range.
Full protection features include SCP, OCP, UVP, and thermal shutdown.
The MP9447 requires a minimal number of readily-available, standard, external components, and is available in a space-saving 3mm×4mm, 20-pin, QFN package.
